Oulujärvi

Oulujärvi is a vast lake in Kainuu, its open waters divided by Manamansalo, a large island of sandy ridges. A church was established on the island in the sixteenth century but destroyed during wars between Sweden and Russia. Boats later carried tar from the forests of Kainuu across the lake towards Vaala and down the Oulujoki, sheltering in the channels around the island when weather turned rough.
